Description

Selecting the AF Point  (EOS Rebel T7)
 

Solution

In Basic Zone modes, the camera will normally focus on the closest subject automatically. Therefore, it may not always focus on your target subject.
In the  modes, you can select one AF point and focus only on the area covered by that AF point.
 
Press the  button .
  • The selected AF point will be displayed on the LCD monitor and in the viewfinder.
Select the AF point.
  • Use the  cross keys to select the AF point.
  • While looking through the viewfinder, you can select the AF point by turning the  dial until the desired AF point lights up in red.
  • When all the AF points light up, automatic AF point selection will be set. The AF point will be selected automatically to focus on the subject.
  • Pressing toggles the AF point selection between the center AF point and automatic AF point selection.
Focus on the subject.
  • Aim the selected AF point over the subject and press the shutter button halfway to focus.

Shooting Tips

When shooting a portrait up close, use One-Shot AF and focus on the eyes.
  • If you set the composition after focusing on the eyes of the person to be photographed, the vivid facial expression will stand out more in the picture.
  • If it is difficult to focus, select and use the center AF point. The center AF point is the most sensitive among the nine AF points.
  • To make it easier to focus on a moving subject, set the camera to automatic AF point selection and AI Servo AF. The center AF point will first be used to focus on the subject. During autofocusing, if the subject moves away from the center AF point, focus tracking continues as long as the subject is covered by another AF point.

AF-Assist Beam with the Built-in Flash
Under low-light conditions, when you press the shutter button halfway, the built-in flash may fire a brief burst of flashes. This illuminates the subject to help autofocusing
  • AF-assist beam will not be emitted from the built-in flash in  mode, or when [Built-in flash firing] is set to  mode.
  • The AF-assist beam will not be emitted with AI Servo AF operation.
  • The effective range of the AF-assist beam emitted by the built-in flash is approx. 4 meters / 13.1 feet.
  • In Creative Zone modes, when you raise the built-in flash with the <> button, the AF-assist beam will be emitted as necessary. Note that the AF-assist beam will be emitted according to the setting of [7: AFassist beam firing] under  [3: Custom Functions(C.Fn)].

If you use an Extender (sold separately) and the maximum aperture becomes higher than f/5.6, AF shooting will not be possible (except in  during Live View shooting). For details, refer to the Extender’s instruction manual

Subjects Difficult to Focus on
Autofocus can fail to achieve focus (viewfinder’s focus indicator  blinks) with certain subjects such as the following:
  • Subjects with very low contrast (Example: Blue skies, solid-color flat surfaces, etc.) 
  • Subjects in very low light 
  • Strongly backlit and reflective subjects (Example: Cars with highly reflective bodies, etc.) 
  • Near and distant subjects framed close to an AF point (Example: Animals in cages, etc.)
  • Subjects such as dots of light framed close to an AF point (Example: Night scenes, etc.)
  • Repetitive patterns (Example: Skyscraper windows, computer keyboards, etc.) In such cases, focus by doing either of the following: 
(1)With One-Shot AF, focus on an object at the same distance as the subject and lock the focus, then recompose the shot.
(2) Set the lens’s focus mode switch to <MF> and focus manually.
  • Depending on the subject, focus may be achieved by slightly recomposing the shot and performing AF operation again.
  • For subjects difficult to focus on during Live View shooting with ,
